It is the far distant future. Humankind, or that which came after, once spread amongst the stars. Those stars have long since dwindled, and the last light has faded. The inevitable and eventual heat death of the universe approaches.

You find yourself drifting alone in this omnipresent darkness. With no light, and limited energy, your only hope of survival is to siphon what little power remains from long abandoned ships and deep space probes.

You have discovered that a few of these objects still respond to your broadcasts. By listening to their faint reply you should be able to pinpoint their location. With some luck you might even reach them before you lose all power yourself.
